Patented Dec. 9, 1930 UNITED STATES PATENT OFFICE JOHN S. STOKES, OF HUNTING-DON VALLEY, PENNSYLVANIA, ASSIGNOR TO STOKES AND SMITH COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN-' SYLVANIA PACKAGE, WRAPPER, AND METHOD OF APPLYING WRAPPERS TO CONTAINERS Application filed January 8, 1926. Serial No. 79,936.

My invention relates to the application of individual, previously prepared sheets, labels, wrappers, or equivalent, hereinafter generically termed wrappers, to previously completed closed container structures, boxes, or equivalent, hereinafter generically termed containers, whereby there are produced Wrapped containers, hereinafter generically termed packages.

More particularly, my invention comprehends the enclosure of a non-cylindrical closed container, as one that has three or more sides and two ends, by an individual Wrapper suitably reinforced in those regions adjacent or overlying the corners of the container.

In accordance with my invention, an individual wrapper of any desired shape or configuration and of suitable material, as an inexpensive grade of wrapping paper, is strengthened or reinforced ina plurality of predetermined regions by adhering structures of paper, cloth, or equivalent, whereby upon application of the wrapper to a container the resultant package Will be reinforced or strengthened in those regions where fracture might otherwise occur.

Further in accordance with my invention, an individual wrapper comprising a plurality of reinforcing elements adhering thereto in predetermined positions is applied to all six sides of a square or rectangular container confining a substance, as a food-stuff, in such manner that each of the reinforcing elements, aforesaid, shall overlie a corner of the container on all container faces meeting thereat. Further in accordance with my invention, there is applied to a non-cylindrical closed container an individual wrapper comprising a plurality of reinforcing elements located in predetermined positions and,oupon completion of the wrapping operation, overlying the corners of the container.

Further in accordance with my invention, individual reinforcing elements after application thereto of suitable glue or adhesive are applied in predetermined regions to an individual, previously prepared Wrapper of any desired configuration whereupon preferably the entire face of the combined Wrapper structure including the exposed faces of the reinforcing elements is coated with suitable glue or adhesive, and before substantial setting or hardening of the adhesive the wrapper is applied to the various faces of a container in succession with each reinforcing element adheringto and overlying a corner of the container on all container faces meeting thereat.

In accordance With my invention there may be an individual reinforcing element for each container to be reinforced, or a single reinforcing element may have an extent such that it suffices to reinforce two or more corners of the container.

My invention resides also in an individual wrapper per se, having reinforcing elements applied thereto at regions destined to overlie container corners; and in a notched, individual wrapper provided with reinforcing elements notched in register with the wrapper notches.

My invention further resides in a package per se comprising a previously completed closed container having therein material, as a food-stud, and enclosed by a Wrapper comprising reinforcing elements overlying the corners of the container, and more particularly my invention resides in a composite package wherein reinforcing elements, as aforesaid, overlie the ends and sides of a container at the corners thereof.

In another aspect, my invention resides in a notched wrapper adapted to be applied to a box, having reinforcing elements applied thereto which extend across or bridge the notches, and particularly at their apexes.

My invention resides in the method and products or articles hereinafter described and claimed.

For an understanding of my method and for an illustration of my products or articles, reference is to be had to, the accompanying drawing, wherein:

In the accompanying drawing and description the container P, P1 or P2, etc., is of any suitabletype or structure, and more particularly, may be of the folding carton type or of the sealed carton type, including the Brightwood carton.

Referring to Fig. 1, there is illustrated an individual wrapper B of suitable material,

as paper, notched along opposite ends thereofto provide a series of upper end panels a, a1, a2 and a3 and a series of lower end panels 6, b1, b2 and 123, each of saidend panels being foldable into engagement with the ends of a. container, as hereinafter described.

As indicated by the dotted lines in Fig. 1, it mai be assumed that wrapper B comprises a tuc -up 0 adapted to be initially secured to the proper part of a container as the back thereof. Wrapper B may also be assumed to comprise a plurality of similar rectangularsections (1, d1, d2 and d3 adapted to be sequentially secured, respectively, to the bottom, front, back and top of the container in the order named. It is to be understood, however, that the dotted lines described above are merely representative of the positions assumed by various parts of the wrapper with respect to the container to be outer edge of the tuck-up 0.

wrapped and that in practice the wrappers comprise plane or substantially flat sheets, unscored and unlined, of suitable material and usually, although not necessarily, notched along opposite ends thereof. Wrapper B may also be provided with a printedorv lithographic designation of suitable character.

In accordance with my invention, wrapper B, in each region thereof where contact is effected with the corner of a container, is formed substantially thicker than in regions removed a substantial distance therefrom. To this end, wrapper B may be provided with a reinforcing element or a plurality thereof of suitable material, which may be paper of a weight corresponding with that of wrapper B, or of different weight as desired. It is characteristic of my invention, however, that the utilization of reinforcing elements for the corners of the container greatly broadens the range of weight of wrapping material that may be assumed by the wrapper, and, therefore, it becomes practical to use a grade of relatively thin paper.

Along the upper part of the wrapper B as illustrated in Fig. 2, I place a plurality of such reinforcing elements 6, el and 62, of any desired shape but preferably rectangular or square, disposed on the wrapper in positions to overlie or bridge the apexes of the notches between wrapper panels a, (11, etc., described above. A fourth reinforcing element 63 having a shape corresponding generally with that of elements e, 01 and 02 is carried by wrapper B substantially in horizontal alignment with said last-named elements when the wrapper is in the position indicated in Fig. 2, the outer edge of said element 63 lying substantially in a vertical line included in the Upon completion of the container-wrapping operation, the reinforcing elements described above will be found to have assumed a position around each of four trihedral corners of the container at one end thereof.

Along the lower part of Fig. 2, I have indicated a plurality of reinforcing elements f, f1, f2, and f3 corresponding with the elements 6, 61, etc. When wrapper B is posi tioned as indicated in Fig. 2, elements f, fl, etc., are substantially in vertical alignment with the corresponding elements 6, 61, etc., located thereabove.

\Vith the construction illustrated at the bottom of Fig. 2, it will. be observed that which it is characteristic that the reinforcing elements or tabs 6, e1, etc, and 7", f1, etc., do not overlie the notches between the wrapper panels, but have their upper and lowermost edges disposed substantially at the apexes of'the notches between the wrapper panels. In this case the distance between the upper and lower apexes between the wrapper panels is slightly greater than the length of the container, whereby when the container is wrapped the tabs or reinforcing elements e, e1,etc., and 7, f1, etc., will each be applied to three intersecting faces of the container at a trihedral corner.

In Fig. 2b is illustrated a further modification of which it is characteristic that the reinforcing tabs or elements 6, 61, etc., and 7, fl, etc., are themselves notched in register with the notches between the wrapper panels. In applying a wrapper so provided with notched tabs or reinforcing elements, each tab or reinforcing element is applied to three intersecting faces of the container at a trihedral corner thereof.

It shall be understood that the reinforcing elements e, 61, f, f1, etc., may be obtained from a suitable source of supply, as from tapes or rolls, or from previously prepared stacks of individual elements. After said elements are coated preferably on but one face thereof with suitable adhesive or glue, the coated face or surface of individual elements is applied to the wrapper B in the desired regions, either by hand or by suitable mechanism. Preferably, the various reinforcing elements are not applied to wrapper B until a period just preceding the container-wrapping operation.

Upon completion of the operation described above, suitable glue or adhesive is applied to the exposed faces of the various reinforcing elements, 6, f, etc., and preferably entirely to that face of the wrapper B which is to lie against the various sides of the container. The wrapper thus prepared is indicated in Fig. 3, and is now ready for application to the container, which may be effected in any suitable manner, as by hand, or by mechanism heretofore in use for appl ing non-reinforced blanks to containers. XS described herein, it will be assumed that engagement between the wrapper and container is efiected by mechanism of the character just noted. It is highly desirable that the wrapper be applied to the container before material hardening or setting of the various adhesive coatings that have been applied to the reinforcing elements and wrappers.

In Figs. 411, inclusive, I have illustrated various stages of the wrapping operation from the time that contact between wrapper B and the container P is first effected until completion of the operation.

Having effected interengagement of the wrapper and container as described above,

tuck-up c is folded into engagement with one side of the container, herein termed the back, Fig. 5. In so doing, reinforcing'elements c3 and f3 are likewise folded into ongagement with the back of the container.

Thereafter, by a simultaneous operation, end panels a3 and 63 are caused to engage respective opposite ends of container P while the front side thereof is engaged with section 032 of wrapper B, Fig. 6. With the container in this position, the corners of the container at the intersection of the front and top faces lie, respectively, on those portions of reinforcing elements 01 and fl included in said section 032 of wrapper B.

In the next stage, the top of container P is engaged with section all of wrapper B, and in so doing the corners of said container at the intersection of the top and back faces contact with and lie, respectively, on those portions of reinforcing elements 6 and f included in the section d1 of wrapper B, Fig. 7.

By the succeeding operation, end panels a2 and 62 are folded into engagement, respectively, with the ends of thecontainer, portions thereof overlying portions of end panels a3 and 63, Fig. 8.

Thereafter, engagement is effected between the back of container P and section 03 of wrapper B, Fig. 9.

' End panels a and b are now folded into contact, respectively, with the ends of the container, portions thereof overlying the end panels (13 and a2 at one end of the container and end panels 63 and 62 at the other end thereof, Fig. 10.

As the final stage of the wrapping operation, end panels a1 and bl are folded, respectively, into engagement with opposite ends of the container, portions thereof overlying the end panels a3, a2, and a at one end of the package and end panels 63, b2 and b at the other end thereof, Fig. 11.

It will be observed that the trihedral corners of the completed package are each enclosed on all sides by the reinforcing elements e, 61, 7, f1, etc., which are so positioned on the wrapper B as to co-act with and form a reinforcement for each trihedral corner. Therefore, even though the packages receive rough treatment, there is but little chance that fracture thereof will occur, especially ners, inasmuch as trpart-thereof overlies the to provide a series of upper end panels g, 91, 2, g3 and a series of lower end panels h, 1, k2, 7L3, each of said end panels being foldable into engagement with the ends of a container, in any suitable manner as, for

example, as described above in connection with end panels a, al, b, 61, etc., Fig. 1.

Wrapper B1 may be assumed to comprise a tuck-up 2' adapted to be initially secured to the proper part of the container and may further be assumed to comprise a plurality of similar rectangular sections 9', jl, 7'2, 7'3,

adapted to be sequentially secured, respectively, to the bottom, back, front and top of the container in the order named.

In accordance with my invention, wrapper B1 in each region thereof where contact is effected with a corner of the container is provided with reinforcing structure of suitable material, as paper, preferably of heavier weight than the material forming said wrapper. In this form of my invention, such reinforcing structure comprises a pair of tabs or elements in the form of tapes, webs, or equivalent, secured to, and usually extending substantially parallel one with the other longitudinally of the wrapper.

In Fig. 13, along the upper part of wrapper B1, there is illustrated a corner and edge reinforcing tape or web is carried by said wrapper overlying the apexes of the notches between the end panels g, 91, etc. Upon completion of the container-wrapping operation, the reinforcing tape or web lo will be found to have assumed a position substantially encircling the container at one end thereof and when carried by wrapper B1 in the position indicated above, said tape or web will ordinarily be folded 0r tucked around into engagement with the adjacent end of the container, the result being that the trihedral corners thereof are strengthened or reinforced upon all of the various sides thereof.

Along the lower part of Fig. 13, I have shown a tape or web m of the same character as web is, similarly positioned and applied in like manner to the trihedral container cornotches between the respective end panels h, 71.1, etc.

In Fig. 13a the arrangement is similar to .that of Fig. 13 except that the continuous or elongated reinforcing elements or tabs in and m are positioned with their upper and lower edges, respectively, at the apexes between the wrapper panels g, 91, etc, and h, k1, etc. In this case, as in the case of Fig. 2a, the reinforcing elements or tabs, because the distance between the apexes of the notches between the wrapper panels at the upper and lower ends of the wrapper is somewhat greater than the length of the container P, upon application of the wrapper to the container overlie the three faces at each trihedral corner of the container and between adjacent trihedral corners of the container overlie the edge formed by two intersecting faces, one a side and one an end of the container.

In Fig. 13b the arrangement is generally similar to that of Fig. 2b in that the reinforcing elements or tabs k and m are notched in substantial register. with the notches between the wrapper panels, and when the wrapper is applied to the container these notched reinforcing elements is and m engage the three faces of each trihedral corner of the container and, between the adjacent trihedral corners, each tab is applied around the edges formed by the intersecting sides and ends of the container.

Tapes or webs is and m may be withdrawn from a suitable source of supply, and after one face or surface of each is coated with suitable adhesive or glue, they may be up plied to wrapper B1 in the desired regions, either by hand or by suitable mechanism. Upon completion of this operation, there is enected an application of suitable glue or adhesive to the exposed faces of the tapes or webs k and m, and preferably entirely to that face of the wrapper B1 which is to lie against the various sides of the container. The wrapper thus prepared is indicated in Fig. 14, and should preferably be immediately applied to the container, which maybe effected in any suitable manner, as by hand, or by mechanism of the character noted above with respect to Figs. 1, 2, et seq.

in Figs. 1-14., inclusive, I have illustrated individual wrappers B and B1, the former having individual corner-reinforcing elements adhering thereto for each trihedral corner of the container, and the latter provided with corner-and-edge-reinforcing tapes or webs. There are many types of wrappers in use, the configuration or size thereof depending largely upon the shape of the container and the'manner in which the wrapper is to be applied thereto. Some of these wrappers are notched or scored along opposite ends thereof in a manner substantially different from that indicated in Figs. 1 to 14, inclusive. However, it shall be understood that no matter what the configuration of the individual wrapper or the manner of notching thereof, it is within the scope of my invention to apply thereto in desired regions either reinforcing elements of the character illustrated in Figs. 1 to 11, inclusive, or reinforcing tapes or webs of the character illustrated in Figs. 12, 13 and 14, or other suitable reinforcing or strengthening structure.

Further itshall be understood that my invention may be practiced when utilizing individual wrappers whose opposite ends or edges are not scored or notched. For example, in Fig. 15 there is illustrated a wrapper B2 of generally rectangular shape, although it is to be understood that the shape of the illdividual wrapper may vary within wide limits depending usually on the configuration of the container or upon the manner of wrapping the same. Wrapper B2 may also be assumed to comprise a tuck-up p and rectangular sections q, 1, 2, and g3, adapted to be sequentially secured, respectively, to the bottom, back, front and top of the container in the order named. For the purpose of this description, it will be assumed that in Fig. 18, the lower surface or face is the bottom of the container while the surface or face toward the right, Fig. 18, is the back of the container. Accordingly, no matter what the position of the container. these faces will be designated, respectively, as the bottom and the back, other surfaces or faces of the package in each case being given their obvious and proper designations.

In accordance with my invention, wrapper B2, spaced from one end thereof, is provided with a plurality of reinforcing elements 1', r1, T2 and 7'3, and spaced from its-other end, said wrapper is provided with a series of similar reinforcing elements. 8, s1, s2 and 83. It is to be, understood that the various reinforcing elements are preferably so positioned on wrapper B2 as to overlie the trihedral corners of the container on all sides thereof upon completion of the wrapping operation. To this end, parts of reinforcing elements 9", 11, etc., should overlie end panel n, while parts of reinforcing elements 8. .91, etc., should overlie end panel 0. It is to be understood, however, that such reinforcing elements may be otherwise positioned suitably to engage or adhere to intersecting faces at or between trihedral corners of the container.

Reinforcing elements 7-, r1, 8, 81, etc., may

be derived from a suitable source of supply, and after application to one side or face thereof of suitable glue or adhesive, may be applied to wrapper B2 in the desired regions, either by hand or by suitable mechanism. Thereafter, there is effected an application of suitable glue or adhesive to the exposed faces of said reinforcing elements, and preferably entirely to that face or wrapper B2 which is to lie against the various sides of the package. The wrapper thus prepared is indicated in Fig. 17. and preferably should be immediately applied to the container, which application may be effected in any suitable manner, as by hand, if desired. In Figs. 18 to 26, inclusive, I have illustrated various stages of the wrapping operation from the time that contact between wrapper B2 and container P2 is first effected until completion of the operation.

Initially, one side of container P2, as the bottom, is caused to register and contact with that portion of the wrapper defined by the rectangular section 93, in which position said container lies between the end panels n and 0. When so located, the bottom of container P2 at its various corners is in engagement with parts of reinforcing elements .12, T3, 82 v and s3.

Having effected inter-engagement of the wrapper and container in this manner, tuckup 1) is folded into engagement with one side thereof, as the back, Fig. 18. In so doing, parts of reinforcing elements 1'3 and 83 are folded into engagement with said back of the container.

Thereafter, contact between the section 92 of the wrapper and the front of the container is effected, whereby parts of reinforcing elements T1 and 81 are brought into engagement with the opposite corners of the container lying at the intersection of the top and front faces thereof, Fig. 20.

In the next stage of the operation, engagement is effected between section 91 of the wrapper and the top of the container. At

this time, parts of reinforcing elements 7" and,

8 are brought into engagement with the opposite corners of the container lying at the intersection of the top and back faces, Fig. 21.

As the next step of the wrapping operation, engagement is effected between the section q of the wrapper and the back of the container, whereby the free end of section 9 is caused to overlie the tuck-up 12, Fig. 22.

The container is now entirely encircled by the wrapper, and, to complete the wrapping operation, it is only necessary to fold the end panels n and 0 into engagement with the ends of the container. This operation may be effected, for example, in a manner similar to that ordinarily practiced when wrapping a container by hand.

Initially, the portions of end panels n and 0 lying substantially in alignment with the back of the container are folded inwardly into engagement, respectively, with the opposite ends thereof, Fig. 23, whereafter the portions of said end panels lying substantially in alignment with the front of the container are likewise folded into engagement, respectively, with said ends of the container, Fig. 24. 7

As the succeeding step in this operation,

the portions of end panels n and 0 lying sub stantially in alignment with the bottom of the container are folded inwardly into engagement, respectively, with the opposite ends of the container, Fig. 25, and, as the last step, and to form the package, the portions of end panels lying substantially in alignment with the top of the container are likewise folded inwardly into engagement, respectively, with said ends of the package, Fig. 26.

Referring to Figs. 27 28 and 29, there is shown at B3 an individual Wrapper of any desired configuration having end panels I? and u which are regular or unnotched. Wrapper B3 may be applied to a container in any desired manner, for example, as described above With respect to Figs. 18 to 26, inclusive.

This form of my invention is exemplary of the use of one or more tapes or webs as strengthening or reinforcing structure for an unnotched wrapper of the character shown in Fi 2-7.

Re erring particularly to Fig. 28, a pair of tapes or webs 'v and w are shown as secured to the wrapper in substantially parallel relation one with the other. Preferably such tapes or webs o and w are so positioned, either as illustrated or in equivalent manner, with respect to the end panels t and u that, upon completion of the wrapping operation, parts thereof will be folded or tucked around into engagement with opposite ends of the container whereby the trihedral cornersthereof are strengthened or reinforced upon all sides thereof.

In Fig. 29 the faces or outer surfaces of wrapper B3 and tapes or webs 'v and w are shown in their coated condition ready for application to the container, which should be effected before substantial hardening or setting of the various adhesive coatings.

Although the foregoing description is limited to application to the wrapper of suitable glue or adhesive after the various reinforcing elements, tabs or tapes have been applied thereto, it shall be understood that this sequence of operation need not necessarily be followed. For example, it is within the scope of my invention to apply suitable glue or adhesive to one face of the wrapper illustrated in Figs. 1, 12, 15 or 27, whereafter the desired reinforcing structure or elements may be applied thereto either in a coated or non-coated condition, generally in accord with my invention disclosed in my co-pending application Ser. No. 81,175, filed Jan. 14, 1926, and the wrapper with thereto-adhering reinforcing elements or tabs is then applied to the container before setting or drying of the adhesive coats upon the container-engaging faces of the wrapper and of the reinforcing elements or tabs.
